A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675
t= log 18.6/ log 1.0675
t=44.75 years
1.5 is the area which makes it the diameter
Answer:

Step-by-step explanation:
This shows the correct way to use the <em>Associative</em><em> </em><em>Property</em><em> </em>because there are GROUPING SYMBOLS wrapped around UNIQUE parts of each expression, and STILL gets the exact same result.
I am joyous to assist you anytime.
97, 19+(11+37)=19+(48)=67 and then add 30 because of 19 and 11 and you get 97
(a+b)² can also be written as (a+b) (a+b). When you expand this you get a²+2ab+b²
(a-b)² can also be written as (a-b) (a-b). When expanded this gives a²-2ab-b2
As you can see, this leads to different coefficients of the 'ab' values: for (a+B) ² its 2 for (a-b) ² its - 2
